A afirmação a seguir apresenta alguns dos fundamentos de circuitos elétricos.
“... the algebraic sum of the voltages around any closed path in a circuit is identically zero for all time, and the algebraic sum of the currents injected in any closed surface is identically zero, also for all time ...” A afirmação indica queO texto a seguir descreve fontes de energia comumente utilizadas pela humanidade.
“... in one hand there are renewable resources, which are resources continually replenished, such as sunlight, wind, tides, waves and geothermal heat. On the other hand, there are non-renewable resources, which are resources consumed much faster than nature can generate them, such as coal, petroleum, and natural gas ...” Segundo o texto,A afirmação descreve um arranjo experimental composto por um amplificador operacional utilizado como subtrator.
“An ideal operational amplifier acting differentially as a subtractor, has an unitary gain. In this case, the output signal is given by the difference from the voltage signal connected to the negative terminal of the op-amp to the voltage signal connected to the positive one. When the voltage signal connected to the negative terminal is fifty volts (positive) and the voltage signal connected to the positive terminal is one hundred and fifty volts (negative), the output signal is two hundred volts (positive).” O texto descreve um arranjo experimental composto por um amplificador operacional na configuraçãoA afirmação descreve um equipamento elétrico empregado em sistemas elétricos de potência.
“The winding resistances of an ideal transformer are negligible, all the flux is confined to the core and the permeability of the core is infinite.” De acordo com a afirmação, um transformador ideal possui enrolamentos com resistênciaA seguinte afirmação apresenta considerações acerca do projeto de máquinas elétricas.
“There are numerous inherent shortcomings to the concept of magnetic circuits, except for the fact that it is the easiest design tool available for calculating fluxes in practical machinery design. Although the use of Maxwell’s equations produces exact results, this method demands considerable effort and does not present significant benefits, when compared to the results produced by the magnetic circuits’ method.” Assinale a alternativa que melhor descreve a afirmação.Um antônimo para a palavra biggest é
